If (x2 - 4) + (x + 2) = x - 2, which polynomial should fill in the blank below?
eOf
=x²-4
(x+2)
x2-4
O x-2
x + 2
x2–2

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
